A spring of negligible mass has force constant (a) How far
Chapter 7, Problem 7.19(choose chapter or problem)
A spring of negligible mass has force constant k = 1600 N/m. (a) How far must the spring be compressed for 3.20 J of potential energy to be stored in it? (b) You place the spring vertically with one end on the floor. You then drop a 1.20-kg book onto it from a height of 0.80 m above the top of the spring. Find the maximum distance the spring will be compressed.

ANSWER:Step 1 of 5
(a) We know that the elastic potential energy is given by equation (7.9)
…. Equation 1
Solving for , we get
We know that the force constant is
